Iris unguicularis aka Algerian Iris

Taxonomy

Iris unguicularis, also known as Algerian Iris or Iris stylosa, is a rhizomatous flowering plant native to Greece, Turkey, Western Syria, and Tunisia. It grows up to 30 centimeters in height and has grassy evergreen leaves. The plant produces pale lilac or purple flowers with a central band of yellow on the falls. These highly fragrant flowers bloom during winter and early spring, boasting pronounced perianth tubes that can reach up to 20 centimeters in length. Iris unguicularis is widely cultivated in temperate regions and has various cultivars available for garden use, such as the slightly more tender white form 'Alba' and the dwarf variety I. unguicularis subsp. cretensis. One notable cultivar, 'Mary Barnard', has been awarded the Royal Horticultural Society's Award of Garden Merit. Another evergreen variety, 'Kilndown', forms clumps and grows up to 40 centimeters tall. It features narrow green leaves and sweetly scented, pale violet-blue flowers that open from mid-winter to spring. This fabulous iris is cherished for its unique bloom time, flowering when very few other plants are emerging. The flowers of Iris unguicularis range from lavender to deep violet and measure 2-3 inches wide (5-8 cm).

How to care for Algerian Iris

Difficulty

If you're looking for a plant that offers a moderate level of challenge, Algerian Iris is a great choice to test your gardening skills.

Water

Algerian Iris should be watered regularly, allowing the soil to dry out between waterings.

Soil

Algerian Iris is very sensitive to dry soil. To ensure your Winter Flowering Iris is thriving and blooming, choose a potting soil that retains moisture. A good soil should still allow for adequate drainage and contain lots of organic matter. Coco coir or sphagnum moss are great soil additives that will help to retain moisture and provide your Winter Flowering Iris with the nutrients it needs for healthy growth. Make sure to mix these soil additives into the potting soil before planting and water the soil thoroughly. By providing your Algerian Iris with a well-draining, moisture-retaining soil, you can help to maximize its growth and keep it blooming.

Lighting

To ensure optimal growth, the Algerian Iris prefers bright indirect light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.

Dormancy

During the cold period, it is common for Algerian Iris to go dormant, resulting in a slowdown of growth. To accommodate this, waterings should be spaced out more.

Toxicity

There is no verified data on the toxicity of this plant in the records of Ploi. If any person, including yourself, a family member, or a pet, consume plant material with an uncertain toxicity level, it is advisable to seek the advice of a healthcare expert.

Fertilizer

Repotting the Algerian Iris should be done either when it has doubled in size or on a yearly basis, whichever occurs sooner. Fresh potting soil with all the required nutrients, refreshed annually, will provide the plant with all the necessary sustenance, making the use of fertilizer unnecessary. Keep in mind that plants receive their energy from the sun, not fertilizer.

Growth-pattern

Clumping is a defining characteristic of the Algerian Iris, with new growth appearing from the soil surrounding the primary plant.
